Part of my job includes directing a child development center. We are a full-time facility, open 7:30-6pm daily, with minimal holiday closings.
You can't really compare blanket child care costs; there are too many variables.
A non-profit center (which is what we are) typically can afford to offer lower rates but only after they have established themselves. The initial cost to open a center is HUGE. The licensing requirements that we follow even after opening are mostly unseen by parents yet very costly on a regular basis to maintain. We certainly aren't making bank on the program.

Since we're a non-profit, all funds go back into our program.
Just some variables to consider when comparing:
What education level do your teachers have? In my state, a faith based center has NO education requirements. Meaning, I'm required to hire someone who's 18 and literate. That's ALL. A disgrace if someone actually follows it! Star rated centers have higher education requirements but not by much.
How much continuing education do they participate in?
Are they CPR/SIDS/First Aid trained?
What is their pay scale for teachers?
What benefits do their teachers get?
What is the turnover like? Both with teachers AND families?
What is the ratio and classroom size for each age group?
How often are supplies, toys, and equipment replaced?
How much of the resources will my child be able to use? Or are teachers limited on consumable resources due to cost?
What outdoor space are they allowed to use and what does it consist of?
What quality of food are they getting?
What kind of curriculum are they using?
What kind of benchmarks are being met at each developmental stage?
What is their sanitation and licensing rating?
What is included in the cost, and what do you have to provide?
Some of my children spend more time with us than anyone else in their life. The quality of program directly impacts their physical, emotional, spiritual, and educational development so it's my top priority. In addition, a lecture I went to last week stated that our kindergartners today are equivalent to a 2nd grader 30 years ago in regards to educational expectations. They are leaving our center and walking into 2nd grade. How are we preparing them? I'm anti overly structured programs but do expect developmentally appropriate structure, classroom management, center based activities, enrichment programs, etc. Perhaps similar to what others have said that a preschool offers, a quality daycare/child development center will do the same.
For me, I've found that investment in my staff is the key. Most of them have been with the program for 10+ years and they attend the birthday parties, graduations, baptisms, etc for these children years after they leave us. The families consider them an extension of their family and it pays off for all involved. I've been in centers that were the opposite (high turnover, little parent connection with teachers, low expectations) and it's just a different beast. The children were safe and minimal standards were being followed but it wasn't best practice IMO.
So all that novel to say, the only way to truly compare costs is to compare similar centers in your city. And if you are in a city like mine, don't wait a minute before looking for infant care! It's very hard to find here and I've had many parents wait too late to get in anyplace and scramble. I'm usually the first person to find out someone's pregnant - even before their parents! - because they are already touring centers to get on wait lists at 6 weeks pregnant.
